Hydrogen sulfide has important biomedical significance because it plays a regulatory role in a variety of physiological processes. In our previous work, we investigated the effect of substituents on Stokes shift of BODIPY and found that methoxy groups on phenyl substituents at 3,5-positions could expand the Stokes shift of BODIPY-based probes. In this study, taking hydrogen sulfide (H2S) as analyte
硫化氢具有重要的生物医学意义,因为它在多种生理过程中起着调节作用。在我们以前的工作中,我们研究了取代基对BODIPY斯托克斯位移的影响,发现在3,5-位的苯基取代基上的甲氧基可以扩大基于BODIPY的探针的斯托克斯位移。在本研究中,我们以硫化氢(H 2 S)为分析物,设计合成了4,4-二氟-8- 4-(2,4-二硝基苯氧基)苯基} -3,5-双(2,4-二甲氧基苯基)-4-硼-3a,4a-二氮杂-小号-indancene(DMOEPB)和4,4-二氟-8-(4-硝基苯基)-3,5-二(2,4-二甲氧基苯基)-4-波拉-3a,4a-二氮杂-小号-indancene(DMONPB)根据相同的策略。如预期的,分别获得了49 nm和51 nm的斯托克斯位移,这证明了该策略在其他荧光探针合成中用于检测小生物分子的可行性。DMONPB可以与H 2 S反应形成衍生物,其荧光量子产率为0.13。在H 2
